Not that

For heavy squats in a CrossFit week, buy the Rehband RX 7mm. It costs less, it's built to move, and it goes in the washing machine. Save the SBDs for the platform.
Brand list prices checked October 27, 2026; Amazon prices change often, so check the current price there. RX Knee Sleeve 7mm (pair) in stock at Amazon as of October 27, 2026 (sizes XXS to XXL listed; sold by Rehband).
Why the coach picked it
- Rehband lists a pair at $94.99 vs. $110 for the SBDs. Same 7mm thickness.
- Rehband's patented anatomical shape and 4-panel construction hold the sleeve tight to the joint, and Rehband pitches the RX 7mm for heavy loads with dynamic movement. That matters for squats, cleans and wall balls, not just a slow grind.
- You can machine wash them at 40°C. The SBDs are hand wash only, and you'll want to wash knee sleeves.
- Rehband lists CrossFit and functional fitness as uses, and is honest that 7mm is for short, heavy work, not long metcons. Pull them on for the strength piece.
When the other one is the right call
If you compete in powerlifting or weightlifting and want sleeves cut to the max IPF spec, get the SBDs. They're IPF approved, USAPL/USPA compliant, IWF compliant, and the full 30cm long.
